(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)We present a theoretical method for deriving the stress tensor and elastic response of ordered systems within a Ginzburg-Landau-type density field theory in the linear regime. This is based on spatially coarse graining the ...

Strong enhancement of level densities in the crossover from spherical to deformed neodymium isotopes (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Understanding the evolution of level densities in the crossover from spherical to well-deformed nuclei has been a long-standing problem in nuclear physics. We measure nuclear level densities for a chain of neodymium isotopes ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Sodium and oxygen are prevalent impurities in kesterite solar cells. Both elements are known to strongly impact performance of the kesterite devices and can be connected to efficiency improvements seen after heat treatments. ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)Down conversion of solar UV and blue light is one of the few ways of surpassing the Shockley-Queisser limit of solar cells. One of the most efficient down conversion systems is the Pr3+ - Yb3+ lanthanide pair. However, ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Four different ruthenium(II) complexes were incorporated into the metal–organic framework (MOF) UiO-67 using three different synthetic strategies: premade linker synthesis, postsynthetic functionalization, and postsynthetic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Two end‐member conceptual models are used to describe deformation of the Earth's crust induced by magma intrusion. “Mode I” fracturing assumes tensile or opening‐mode, elastic deformation, while “Mode II” fracturing assumes ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)We report on the structural and magnetic properties of the elusive Jahn-Teller active compound NaCrF3, for first time synthesized in large quantities allowing detailed characterization. The crystal structure of NaCrF3 is ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Abstract We report on the structural and magnetic properties of Li 5+ x Fe 1− x Co x O 4 (0≤ x ≤1).< The system assumes two distinct crystal structures at room temperature (α and β), and shows a transition in preference ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)The occurrence of pre-collisional structural and metamorphic fabrics may control the development of new structures during subsequent orogenic deformation. Structural, petrological and geochronological analyses have been ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)We report on the B-site substitution of Pt for Ni in the system LaNi1–xPtxO3. The system can only be synthesized between x ≤ 0.50, with LaNiO3 (x = 0.00) and the stoichiometric double perovskite La2NiPtO6 (x = 0.50) ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)A series of Cu(I) complexes of bidentate or tetradentate Schiff base ligands bearing either 1-H-imidazole or pyridine moieties were synthesized. The complexes were studied by a combination of NMR and X-ray spectroscopic ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Abstract The Posada–Asinara Line is a crustal-scale transpressive shear zone affecting the Variscan basement in northern Sardinia during Late Carboniferous time. We investigated a structural transect of the Posada–Asinara ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Materials made of indium oxide (In2O3) are now being used as a potential component of the next generation of computers and communication devices. Density functional theory is used to analyze the physical, electrical, and ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2020)The structure of BaLnCo2O6-δ (Ln =La, Pr, Nd, Sm, Gd, Tb and Dy) was studied by the means of synchrotron radiation powder X-ray diffraction, neutron powder diffraction and Transmission Electron Microscopy (TEM), while water ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Field and seismic observations show that numerous sills exhibit lobate morphologies. Each lobe corresponds to a distinct igneous segment exhibiting a finger-like shape, the long axis of which is commonly interpreted as a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)We have measured water uptake and hydration enthalpy in 50% La and Nd doped CeO2, also to be taken as compositions in the series La2−xNdxCe2O7 (x = 0.0, 0.5, 1.0 and 2.0) using combined thermogravimetry (TG) and differential ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2023)Sub-stochiometric nickel oxide (NiOx) films were investigated as a hole selective contact option in silicon (Si) heterojunction solar cells. Numerical simulations were carried out to evaluate the impacts of the NiOx ...
